Its origins remain surprisingly hazy, but the hamburger has been omnipresent throughout the life of anyone capable of reading this sentence. In the United States, it's basically celebrated daily as the national dish. Some reports put the annual total of hamburgers eaten by Americans in the neighborhood of 50 billion. 50 billion. That's an average of three hamburgers per person every week. We probably don't need a dedicated day to celebrate the burger.

Yet, there's a day for that. Of course there is.

May 28 is National Burger Day, and it falls on Memorial Day this year, which is kind of perfect. If you're not celebrating on a grill out in a park, there are many restaurants offering deals to help you celebrate. (If you're looking for a deal instead of hunting down one of the best burgers in the US.)
